Hmmm...
As a foreigner now flying for an orange UK low cost airline, I don´t really agree with the foreing v.s. UK argument about CDA´s.
Except for the LGW and most foreign crew, very few pilots in my current outfit know how to fly a good CDA approach (engines @ flight idle and without speedbrakes!
) and from a training perspective there is a strong emphasis on level segments in the aproach.
From my experience, you will not score ´browny points´ on your line check by making a smooth continuous descent from TOD.
Just my 2 cents...
